Let's list out what we already know:
Alexa's book is into 8 chapters
Rose's book is into 6 chapters
So since they are out of how many chapters, they number of chapters their books are split into will be the denominator of each fraction. Each girl has already read 3 chapters, so they'll have 3 as their numerator.
Alexa: 3/8
Rose:3/6
We can see that Rose is already at half of the book while Alexa's half would be 4/8, and she isn't there yet. So Rose read more of her book.

What are two numbers multiplied together to get 15 but add to be 12?
KiRa [710]
So x times y=15
x+y=12
solve
x+y=12
subtract x from both sides
y=12-x
subsitute
xy=15
x(12-x)=15
distribute
12x-x^2=15
subtract (12x-x^2) from both sides
0=x^2-12x+15
use quadratic formula which is
x=\frac{ -b+/- \sqrt{b^{2}-4ac} }{2a}
where you have
0=ax^2+bx+c
so
a=1
b=-12
c=15
subsitute
x=\frac{ -(-12)+/- \sqrt{-12^{2}-4(1)(15)} }{2(1)}
x=\frac{ 12+/- \sqrt{144-60} }{2}
x=\frac{ 12+/- \sqrt{84} }{2}
x=\frac{ 12+/- 2\sqrt{21} }{2}
x=6+/- \sqrt{21}
x=6+ \sqrt{21} or 6- \sqrt{21} or aprox
x=10.5826 or 1.41742
the numbers are 10.5826 and 1.41742

In a basketball shooting competition, each competitor shoots ten balls which are numbered from 1 to 10. The number of points ear
sp2606 [1]

Answer:

score 35 is not possible

Step-by-step explanation:

Here, the competitor misses exactly two shots

what we have here is that, if we added from the numbers between 1-10 , excluding exactly two numbers, which of the numbers in the option cannot be obtained by this addition

a) 52

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

Total is 55

if we removed (2 and 1)

we get 52

This is a possible score

b) 44

Here, we just have to remove 11

if we take off 10 and 1, we can have 44

c) 41

if we removed 4 and 10 ; we get 41

d) 38

if we remove 17, we get 38

so let us remove 10 and 7

e) 35

here, we have to remove 20

Now, no two numbers added between 1 and 10 exactly will give 20

The highest sum to be deducted is 9 + 10 which is 19

So the lowest possible score is 55-19 = 36

This means that the term 35 is not possible
